TRANSPORT CHALLENGES
• High number of private vehicles (especially, two-wheelers) and number of
vehicle is growing rapidly (25 years)
Source: Polda MetroJaya, 2010
• Changes in modal shares

THE EXISTING PUBLIC
TRANSPORTATION
• For years, to serve commuters who
work in Jakarta, there have been small
number of railway networks which is
inheritance from the colonial era.

• Nowadays, there are 10 lanes, out of 15 lanes in the plan, of busway which serve around Jakarta, besides dozen traditional buses or minibuses managed by private company or individual.

THE PLAN OF TRANSPORTATION
NETWORK
The Government and the
Provincial Goverment of
Jakarta plan to build:
• Six more toll-road enter to
the city (creating big debat)
• Two lanes of monorail (the
construction already started
after six years pending)
• A lane of MRT from the
southern part to the city
center. 11
